Patent JP-H034133-A (JP)
Title: Helium leak detector
Inventor: IGAWA AKIO
IPC: G21C17/06
Filed: 1989-05-31
Abstract: PURPOSE:To improve the working efficiency of a leak test by providing an N2 supply means in such a manner that the means can be connected to and disconnected from a leak line. CONSTITUTION:A valve FV is closed, a valve BP opened and valve BLV closed and an object 1 to be tested is roughly wacuated by a rough wacuation pump RP in the case of carrying out a leak test. The valve FV is opened upon dropping of the measured pressure of the leak line L by a vacuum gage PM 1 to a set value or below. The He in the line appears in an analysis tube 4 through the reverse diffusion in a high vacuum TMP. The leak quantity by the tube 4 is then measured. N2 is supplied from an N2 cylinder 6 to the line L when the valve BV is closed and the valve BLV opened after the end of the measurement. The valve BLV is closed when the vacuum degree of the line L radually decreases and the measured pressure by a vacuum gage PM 2 attains a set value, the test is held to stand by until the measured value falls down to a bockground level while the supplied N2 is discharged by the pump RP. The working efficiency of the leak test is improved in this way.

IPC: B60C11/16
Filed: 1981-09-05
Abstract: PURPOSE:To increase the braking effect, the ahead power, etc., by making a semi-spherical stock project at the middle of the top wall of a pin head end, and specifically forming the cylindrical circumferential wall of the stock. CONSTITUTION:The stock (a) having a semi-spherical part projects approximately at the middle of the top wall 21 of the head end 2 of a spike pin 1, and the stock (a) has the cylindrical circumferential side wall 3 extending from the top wall 21. The circumferential side wall 3 is thinner toward the top wall 21 while it is thicker toward the top surface 4. The spike pin is mounted in a tire in such a way that the head end 2 is exposed to the rubber layer from the tread in a desired length. Thus since the pin 1 can repeatedly be moved back and forth arcuately a little with the center of the bottom wall 7 of the tail end 6 as a fulcrum point as the tire is rotated, the paved road surface is hardly abraided.

Filed: 1987-06-04
Abstract: PURPOSE:To use recognition pattern information in common and to use algorithm to be processed also in common by processing an unstable factor as an event and recognizing various event data by a common format. CONSTITUTION:An event data processing part 3 consists of a difference processing processor and a first Fourier transformation (FFT) processor and executes the matrix difference processing of various even data to abstract the data.
